Our Verdict: Maelstrom Soft-Sided Cooler Bag (30/40 Can)
A high capacity budget cooler with lots of pockets, best for value and volume rather than long ice life or full waterproofing.
A collapsible 30 or 40 can bag with five insulated layers and ultrasonic welded liner that costs far less than the sealed premium coolers.
So, is it any good?
It is one of the cheapest ways to get 30 can plus capacity.
Reviewers say the insulation rivals more expensive name brands for the price.
For the price the pockets and volume are hard to beat, and the liner really does hold melt water in. It is not a sealed floating cooler though, so I keep it upright and do not trust it in a capsize.

Our Analysis, Comparisons, and Test Results
The Maelstrom Soft-Sided Cooler Bag (30/40 Can) scored 78 out of 100 overall.
It is strongest on value for money and weakest on cold retention.
Here is how it did on every metric we tested, with exactly how each score compares to the rest of the field.
Value for Money
It is one of the cheapest ways to get 30 can plus capacity.
Reviewers say the insulation rivals more expensive name brands for the price.
The value is in volume and pockets, not in premium sealing.
| Value for Money | Rating |
|---|---|
| Best in test | 9/10 |
| Maelstrom Soft-Sided Cooler Bag (30/40 Can) | 9/10 |
| Category average | 7.8/10 |
| Worst in test | 6/10 |
Cold Retention
It is rated to keep contents cold for up to 24 hours, which is best case with heavy ice.
The five layer wall is thinner than the closed cell foam in the top coolers.
Here's what that means:
In real heat expect roughly a day, so over pack ice for anything longer.
| Cold Retention | Rating |
|---|---|
| Best in test | 10/10 |
| Maelstrom Soft-Sided Cooler Bag (30/40 Can) | 5/10 |
| Category average | 6.9/10 |
| Worst in test | 5/10 |
Durability
The ultrasonic welded inner liner resists leaks well.
The oxford and PVC outer layers handle normal use but are lighter than premium shells.
It is a budget build, so avoid dragging it over sharp rocks.
| Durability | Rating |
|---|---|
| Best in test | 9/10 |
| Maelstrom Soft-Sided Cooler Bag (30/40 Can) | 6/10 |
| Category average | 7.3/10 |
| Worst in test | 6/10 |
Features
It holds 30 or 40 cans depending on the size you choose.

| Features | Rating |

| Best in test | 9/10 |
| Maelstrom Soft-Sided Cooler Bag (30/40 Can) | 8/10 |
| Category average | 8.1/10 |
| Worst in test | 7/10 |
Waterproof Features
The welded PEVA liner keeps melt water from dripping out.
The outer zippers are standard, not sealed waterproof zippers, so it is splash resistant only.
Do not count on it to float sealed or survive a dunk like the welded zipper coolers.
| Waterproof Features | Rating |
|---|---|
| Best in test | 10/10 |
| Maelstrom Soft-Sided Cooler Bag (30/40 Can) | 6/10 |
| Category average | 8/10 |
